ton, in the county of Stark and State ofW ilhio, have invented a new and useful Valvehltem Tool, of which the following i speci= iication. i w

Thi invention relatesto improvements in valve stone tools and has more especial referonce to a tool designed to releasectheivalve it is desired. "to re move the tire. i 1 I The objects of the invention are'to sprovidea; device by means of which:the'reinoval of a" pneumatic tire may benroieeasily eifected by releasing the alvestein from the felly of the Wheel. Ari further 'olriect oi the intention is tot: provide a tohl" of the character ll'lBlllllQl'lGCl Wl ich consists of a lever adjustably mounted ripen" the upper end of standard pro nieansfor engaging the valve to n I are}: the loiver endof the standard eing provided Withayolre haped to conform with the huh cap of theordinary auto-" iu'ol'iile Wheel; that the em sunset Q l i ith V inview the invention: consists in the novel construction and arrangement of parts. hereinafter describerh illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form. proportions, size and minor retails of construction may be made Within the scope of the appended claims, Without departing from the spirit or sacrificing any of the advantages of the invention.

The invention thus set forth in general terms illustrated in the accompanying drawings forming part hereof, in Which- Figure 1 is a side elevation of the tool, showing its application to an automobile Wheel.

Fig. 2 a perspective View of the tool; and

Fig. is an enlarged sectional view through the pivotal connection between the post and the lever.

A. practical embodiment of the invention is disclosed in the accompanying drawings forming a part of this specification in which Specification. of

or cannonento.

nilars numerals of reference indicate corresponding parts throughout the several views. i i i i 1 i i w Referring first to j Fig". 1 of the drawings, in which is shown a fragmentary portion of an: automobile 'Wheelpthe numeral 1 indi- .cates the hub :th e numeralfQ, the spokes; the

numeral 2) the fellyy i the T1111, 5 the tire" cas- 111g; 6 the inner tube 1 and 7 the valve stem, :all' of'ivhich partsinay be of any usual and rvvell known"construction. as the'y forin no "part of the invention but are merely illustrated towshoivthe application of thetool. The standard 8 is preferably forlnedgfrom a round rod as shown in the drawings and provided at its lower "end With the' curved yoke 9 arranged to conform" to theacafp of the slidahly i mounted if upon the uprightiand arranged to beheldin any ad justed positionthereon by Iheansmof :aset

screw 12. The, vei'tical'passage lii fthrough which the upr ght is located 1s preferably formed :near one side of the "block: it to perinit: ofthe levenbeing pivoted upon said bloclr Without interfering with the standard 8.

A shouldered bolt 1+1- is passed through a horizontal aperture in the block and through any desired one of the apertures 16 in the lever 17, a thumb nut 18 being placed upon the reduced screvv threaded portion 19 of the bolt and bearing against the shoulder 20 thereon, thus forming a suitable pivot for the lever 17.

By providing a plurality of apertures '16 in the levers 17 any desired adjustment of the lever may be obtained and by adjust" ably mounting the block 11 upon the standard 8, the tool may be adjusted for Wheels of different diameters.

The inner or shorter end of the lever has pivoted thereon a rod 21 having a ball 22 at its upper extremity, this ball being slightly less in diameter than the diameter of the aperture 23 in the felly through which the valve stem is normally located. The rod 21 is pivoted at 24t to the lever W.

in operation the yoke 9* is placed upon the huh as shown "in Fig. l. in the proper po Wheel. hub 1;? and provided 4 upon :its inner sition to bring the standard 8 in the same radial ,plane with the .valveistem 7. The

rod2listhen raised into a substantially vertical position, the ball 22 thereon being 5 placed in engagement with the lower end of the valve stem. Downward pressure upon the outer end of the lever 17 will force the ball 22 upward through the aperture 23 in the telly forcing the valve stem entirely out of the aperture in the telly. When the lower end of the valuestem has clearedthe rim, the stem may be bent to either side of the-aperture: through the: telly. preventing it from .again entering the aperture after which the tool may be removed fromthe wheel-.and the tire removed in the vusual manner (It \villuot' course beunderstood thatthe -.block 11.m ust;be properly adjustedupon thestantla-rd 8 and the. lever .17 be. properly adjusted upon the block 11 to accommodate the.- particular- Wheel upon-which; the device .;is.;i.ise'd'beore theitootis operated. These vadjustments ..are very quickly and easily 25 madeyand of course are unnecessary, excepting in. cases wherethetool is .nsed upon xvheehot'adiitlerent dimensions, as When the tool is onceadjnstedafor. any particular size :ofavheel, it may .be .used continuously upon wheels .of thatsizewithout any adjusting I-being necessary.

.Azlthougli. the drawings andabove specification disclose the best mode in which Iahave contemplatedembodying my invention I de- 7 sire. tObQnIlOil limited, to thedetails of such I .disclosure,-.f.or,in!the further practical ap- ';pl-ication of imyinvention, many. changes in form. and construction may be made, as circumstances.reqnire or experience suggests, 40 AVltllOUt departing fromthe spirit of the va curved yoke: upon the standard adapted .to

lit the hub of a wheel, a lever pivotally connected to the standard, intermediate its ends and .a. valve stem engaging rod pivotally connected to one end of said lever.

B. A valve stem tool, ineluding a. standard, .a yoke uponthe standard adapted to lit the hub of a wheel, ailever pivoted intermediate its ends upon the standard, a valve stem engaging rodprvoted upon one end of thelever and a ball upon the outer end of said rod.

4. A valve stem tool, including a standard, a yoke upon the standard adapted to fit the hub of a wheel, a, block adjustahly mounted upon the standard, a. lever pivotally mounted intermediate its ends upon the block anda valve stemengaging rod pivoted to one end of the lever.

5. A valve stem tool, including a stand- .ard, a yoke upon the standard adapted to fit thehub of a wheel. a block :uljnstalily mounted upon the standard, a lever pivoted intermediate its ends upon the block. means for adjusting the lever upon the block and a valve stem engaging rod pivoted to one end of the lever.

In testimony that l claimthe above, I have hereunto subscribed my name.
